The exact value of the y in the similar right triangle is 2.2360679775 units

<h3 /><h3>How to find the side of a triangle?</h3>

The triangles are similar.

Similar triangles have corresponding sides of equal ratio.

The corresponding angles of similar triangle are equal.

Therefore, using similar ratio,

y / 5 = 1 / y

cross multiply

y × y = 5 × 1

y² = 5

square root both sides

y = √5

Therefore,

y = 2.2360679775 units

The distance between Dallas and Fort Worth on a map is 7.5 centimeters. The map uses a scale in which 1 centimeters represents 3
anyanavicka [17]

Hi There


To find the distance, you have to make them proportional to each other.


1 cent.  / 30 kilo. = 7.5 cent. / x


Then you cross multiply.


30 x 7.5 = x


225 = x


The distance between the two cities is 225 kilometers.


Hope that helps:)

I need to find AB and DE​
MatroZZZ [7]

Answer:

AB = 21 and DE = 23

Step-by-step explanation:

Given 2 intersecting chords inside the circle then

The products of the measures of the parts of one chord is equal to the products of the measures of the parts of the other chord, that is

x(x + 13) = (x + 10)(x + 1) ← distribute parenthesis on both sides

x² + 13x = x² + 11x + 10 ← subtract x² + 11x from both sides

2x = 10 ( divide both sides by 2 )

x = 5

Hence

AB = x + 10 + x + 1 = 2x + 11 = (2 × 5) + 11 = 10 + 11 = 21

DE = x + x + 13 = 2x + 13 = (2 × 5) + 13 = 10 + 13 = 23
